Filed Dec. 18, 1928 2 Sheets-Sheet 2 Patented July 26, 1932 UNITEDSTATES :PATENT OFFICE V GEORGE A. SPILLER AND GEORGE T JOHNSON, OFCOLUMBUS, OHIO, ASSIGNORS TOTHE BUCKEYE STEEL GASTINGS COMPANY, OFCOLUMBUS, OHIO noon I Application filed December 1a, 1925. Serial No.326,823.

The present invention pertains to doors, and especially to drop enddoors for open end freight cars of the gondola type.

It is customary to make such doors of builtup construction, and it isknown to those conversant with such matters, that such doors have somevery weak points. The type of car with which such doors are employed, isbecoming more widely used, and is almostinvariably of the lar estcapacity; namely, 7 tons, and they are loaded with all kinds of heavybulk material, including pipes and other, rolling mill products, and allsuch lading has a tendency toshift when the cars are bumped around inservice; and the shifting of the load throws considerable strain uponthe end doors, which in View of the fact that they are separate movablepieces, are not of a construction best suited for resisting such forces.As a result, the end doors bend or bulge outwardly at the top, indicat-7 ing that the pressed steel doors of the conventional design are notasrigid as would seem to be necessary. The bottom of'the door, being toedagainst a door abutment'that is secured to the end sillof the car, iskept in alignment for a while, but assaid abutment is formed of arelatively light sheet metal upturned lip, extending the full width ofthe car, and is not very strong; due to corrosion and rough usage, thevertical lip of the abutment becomes bent, and allows the door to alsobulge outwardly at the bottom.

with additional objects which will appear as the description proceeds,the invention consists in the novel features hereinafter describedindetail, illustrated in the accomend, as shown at 6;

length of the door,

panying drawings, and specifically pointed out in the annexed claims.

.Referringto the drawings,

Fig. 9 is an enlarged elevation of a detail of the door shown in 8.

Fig. '10 is a vertical sectional view 1010 of Fig. 8.

The improved door is of unitary construcon line 'tion, and formed of onepiece of metal, preferably cast, and shaped to provide the requisitestability.

1 designates the main web or wall, bordered by anangular flange 2, whichprovides a channel shaped reinforcement at each edge of the door. Asbestshown in'Fig. 1,

this flange, at the upper end of the door, extends downwardly in theform of a depending skirt 3, which is of greatest depth atits middle 4,and is gradually tapered from this point toward the ends of the door.The flange makes the edge portion of the door extremely rigid, and thedeepening of the part 3 provides increased reinforcement at the top ofthe door, which must resist the greater strain.

Vertical ribs 5 are provi'ded on the inner faceof thedoor, and each ofthese ribs mergesinto themain web 1', the flange 2, and theapron 3, andeach. rib is gradually tapered toward themain web near its. lower A mainhorizontal rib 7 extends the full and its ends merge into the sideflanges at the points 8.

These intersecting vertical and horizontal ribs are also provided withintegral reinforcing flanges 9, which merge into the inner extensions ofthe flanges 2, and the flanges on each vertical rib 5 are integrallyunited with the main web, as shown at 10.

The lower central portion of the door is reinforced by a shorterhorizontal rib 11, having tapered end ortions terminating short of theribs 5, an the rib .11 is also reinforced by oppositely extendingflanges 12 that merge into the web 1. The ribs and their reinforcingflanges may be looked upon as T-shaped reinforcements.

As doors of this type are used in close proximity to the brake wheels atthe ends of the car, the metal of the web is shaped as shown at 18, toprovide a pocket into which the brake wheel may project and allowclearance for the hands of the operator.

Apertured ears 14 are arranged in pairs near the lower side of the doorto form parts of the hinges employed in pivotally connecting the lowerside of the door to the floor of thecar.

By way of reiteration, it may be noted that thetop edge of the door hasa channel construction for increased strength, and the three of itssides. Due to this, the main horizontal rib 7 may be located nearest thetop edge of the door. This main rib and the nearby channel at the topedge, will eliminate bending at and near the top of the door.

As the door forming the subject matter of this invention was designedespecially for use with a car end of the type shown in applicationSerial No. 322,284, filed November 27, .1928, it need not be as rigid atits lower end as. at its upper end, for a heavily reinforced abutment ofthe cast steel car end will prevent bulging along the bottom edge.

The castingmay be made with holes 15 at each end near the upper cornerof the door to receive the rivets employed in connecting the latch linksto the door, or as shown in Figs. 8, 9 and 10, the door may be providedat these points with latch hooks 16 which are integral portions of thecasting that forms the door. Each hook is formed by an upwardlyextending arm 17 reinforced tion at the end of the car.

It is believed from the above description that the construction andadvantages of the invention may be readily understood, and it ismanifest that changes may be made in the structure disclosed withoutdeparting from the spirit of the invention as expressed in the claims.

What we claim and desire to secure by Letters Patent is:
